N1 - Funding Information:
In-situ observations and measurements using synchrotron radiation were performed as general projects at the BL20XU beamline of SPring-8 (JASRI), Japan. The authors acknowledge financial support from the Grant-in-Aid for Scientific Research on Innovative Area “High Entropy Alloys” (No. 18H05455). The X-ray imaging technique was developed with funding from a Grant-in-Aid for Scientific Research (S) (No. 17H06155).

N2 - Time-resolved tomography (4D-CT) and X-ray diffraction (XRD) were combined to observe growing dendrites and to measure their crystallographic orientation in a CrMnFeCoNi high-entropy alloy with an FCC structure. The evolution of the dendritic grains cooling at 0.083 K/s was reconstructed using 200 projections over a 180° rotation every 4 s from 4D-CT and a phase field filter. The voxel size was a 6.5-µm cube. Simultaneously, the crystallographic orientations of the dendritic grains were measured by XRD.
